Bulletin 71.1:67D
Principle of Operation (Figure 2)Downstream pressure is registered internally on the lower side of the diaphragm. When the downstream pressure is at or above the set pressure, the valve plug is held against the orifice and there is no flow through the regulator. When demand increases, downstream pressure drops slightly allowing the spring to extend, moving the stem down and the valve plug away from the orifice. This allows flow through the regulator.
Internal Relief (Types 67DR, 67DSR, 67DFR and 67DFSR) If for some reason, outside of normal operating conditions, the downstream pressure exceeds the setpoint of the regulator, the force created by the downstream pressure will lift the diaphragm until the diaphragm is lifted off the relief seat. This allows flow through the token relief. The relief valve on the Type 67DR, 67DSR, 67DFR or 67DFSR is an elastomer plug that prevents leakage of air from the downstream to atmosphere during normal operation, thereby conserving plant air.
Smart Bleed AirsetIn some cases, it is desired to exhaust downstream pressure if inlet pressure is lost or drops below the setpoint of the regulator. For example, if the regulator is installed on equipment that at times has no flow demand but is expected to backflow on loss of inlet pressure. The Type 67DFR or 67DFSR can be ordered with the Smart Bleed option which includes an internal check valve for this application. During

operation, if inlet pressure is lost or decreases below the setpoint of the regulator, the downstream pressure will back flow upstream through the regulator and check valve. This option eliminates the need for a fixed bleed downstream of the regulator, thereby conserving plant air.
Note
During normal operation the check valve’s metal to metal seat allows limited flow through the regulator from the inlet to outlet, even when there is no downstream demand. To prevent downstream pressure buildup, the Smart Bleed option is only avilable with the internal relief version of the 67 Series.
InstallationThe 67D Series regulators may be installed in any position but vertical orientation is recommended for models with draining features. Spring case vents must be protected against the entrance of rain, snow, debris or any other foreign material that might plug the vent openings. The inlet connection is marked “In” and the main outlet connection is marked “Out”. If a pressure gauge is not installed in one of the two secondary outlet connections, plug the unused connections. See Figures 4 and 5 for dimensions.
Emerson Process Management Regulator Technologies, Inc. provides an instruction manual with every regulator shipped. Refer to this for complete installation, operation and maintenance instructions. Included is a complete listing of individual parts and recommended spare parts.

Bulletin 71.1:67D
Note
The 67D Series regulators may be sized for 100% flow using capacities as shown in Table 4. It is not necessary to reduce published capacities.
To determine the equivalent capacities for other gases, multiply the table capacity by the following appropriate conversion factor: 1.29 for 0.6 specific gravity natural gas, 0.810 for propane, 0.707 for butane or 1.018 for nitrogen. For gases of other specific gravities, divide the table capacities by the square root of the appropriate specific gravity. To find wide-open flow capacities for relief sizing at any inlet pressure, perform one of the following procedures. Then, if necessary, convert using the factors provided above.
For critical pressure drops (absolute outlet pressure equal to or less than one-half of absolute inlet pressure), use the following formula:
Q = (P1)(Cg)
For pressure drops lower than critical (absolute outlet pressure greater than one-half of absolute inlet pressure), use the following formula:
Q CgP1SIN= 520GT
3417C1
) ) PP1
DEG
where,
Q = gas flow rate, SCFH P1 = absolute inlet pressure, psia (P1 gauge + 14.7) Cg = gas sizing coefficient G = specific gravity of the gas T = absolute temperature of gas at inlet, °Rankine C1 = flow coefficient (Cg ÷ Cv) P = pressure drop across the regulator, psi
Then, if capacity is desired in normal cubic meters per hour (at 0°C and 1.01325 bar), multiply SCFH by 0.0268.
NACE Universal ComplianceOptional materials are available for applications handling sour gases. These constructions comply with the recommendations of NACE International sour service standards.
The manufacturing processes and materials used by Regulator Technologies assure that all products specified for sour gas service comply with the chemical, physical and metallurgical requirements of NACE MR0175 and/or NACE MR0103. Customers have the responsibility to specify correct materials. Environmental limitations may apply and shall be determined by the user.
Overpressure ProtectionThe 67D Series regulators have maximum outlet pressure ratings that are lower than their maximum inlet pressure ratings. A pressure-relieving or pressure-limiting device is needed if inlet pressure can exceed the maximum outlet pressure rating.
Types 67DR, 67DSR, 67DFR and 67DFSR regulators have a low capacity internal relief valve for minor seat leakage only. Other overpressure protection must be provided if the maximum inlet pressure can exceed the maximum pressure rating of the downstream equipment or exceeds maximum outlet pressure rating of the Type 67DR, 67DSR, 67DFR or 67DFSR regulator.
Overpressuring any portion of a regulator or associated equipment may cause leakage, parts damage or personal injury due to bursting of pressure-containing parts or explosion of accumulated gas. Regulator operation within ratings does not preclude the possibility of damage from external sources or from debris in the pipeline. A regulator should be inspected for damage periodically and after any overpressure condition.
Refer to the Capacity Information section and the Wide-Open Flow Coefficients for Relief Valve Sizing in the Specifications section on page 3 to determine the required relief valve capacity.
Capacity InformationTable 4 shows the air regulating capacities of the 67D Series regulators at selected inlet pressures and outlet pressure settings. Flows are shown in SCFH (at 60°F and 14.7 psia) and in Nm3/h (at 0°C and 1.01325 bar) of air.
